Ace filmmaker Christopher Nolan has chosen to partner with Universal Pictures for his new movie about American theoretical physicist J Robert Oppenheimer who helped develop the atomic bomb during World War II.

PTI reported last week that Nolan and his representatives were in talks with major Hollywood studios for the untitled project, a move that signaled at the end of his collaboration with Warner Bros.

Since 2002’s Insomnia, Nolan made all of his movies with Warner Bros and that included his critically-acclaimed The Dark Knight trilogy and the most recent feature Tenet.

But relations between Nolan and Warner Bros had soured last year after the filmmaker expressed dissatisfaction with the studio for moving its 2021 slate to a day-and-date theatrical and HBO Max streaming release.

The plot details are sketchy but the new movie will focus on Oppenheimer, who is considered one of the fathers of the atom bomb, PTI reported.

He was a pivotal figure in the Manhattan Project — the World War II undertaking that developed the first nuclear weapons.

Cillian Murphy, one of Nolan’s frequent collaborators, is said to be a possible member of the ensemble, but casting has yet to take place.

Filming on the Oppenheimer picture is expected to begin in the first quarter of 2022.

The project will be produced by Nolan alongside his wife and longtime producing partner Emma Thomas for their Syncopy Inc. banner.

Nolan most recently directed spy thriller movie Tenet, starring John David Washington, Robert Pattinson, Elizabeth Debicki, Dimple Kapadia, Michael Caine, and Kenneth Branagh.

Tenet was the first Hollywood tentpole to open in theatres after the coronavirus pandemic-forced shutdown.
